That statement is a fallacy. Some Americans come from cultures where they hug and kiss a lot--others come from backgrounds that are very reserved, not at all "touchy feely."
I imagine Lord Geidt and Meghan have developed a warm working relationship, hence the greeting.
Agree and thank you for the clarification.
Kissing on the cheek with someone who is barely known to you is not an American thing. In reality 'American' Meghan may need to adjust to that. Its one thing when you know the person well, Sir Geidt she doesn't.
